Is there anyway to make brew's cmake work with system clang?
The question is not correct. CMake uses the system clang successfully, but it can't find clang libraries required by the project.
The Build manual lists the requirements, one of them is
Clang+LLVM headers and libraries, version >= 7
You get errors because you have not provided that dependency.
brew install llvm#13

SUPERDCA_DEPENDENCIES setup: check for Boost
CMake Error at /mnt/d/conda/superdca/lib/cmake/Boost-1.80.0/BoostConfig.cmake:141 (find_package):
Found package configuration file:
/mnt/d/conda/superdca/lib/cmake/boost_program_options-1.80.0/boost_program_options-config.cmake
but it set boost_program_options_FOUND to FALSE so package

package:
No suitable build variant has been found.
The following variants have been tried and rejected:

Since it says it set boost_program_options_FOUND to FALSE, should I set it to TRUE?
The package versions are:
# Name Version Build Channel
boost-cpp 1.80.0 h75c5d50_0 conda-forge
cmake 3.24.1 h5432695_0 conda-forge
The clue is here:
* libboost_program_options.so.1.80.0 (shared, Boost_USE_STATIC_LIBS=ON)
Presumbly your Conda environment has only shared libraries for Boost in $CONDA_PREFIX/lib, and not static ones. For some reason, the software you're trying to build has set Boost_USE_STATIC_LIBS to require static linking. Without knowing why that is, there are two possible solutions:
Find where Boost_USE_STATIC_LIBS is set, and remove it.
Find a Boost package which contains static libraries. This may be fairly uncommon on Linux, where shared libraries are used most of the time.
I am developing on macOS with Apple-clang v12 being the default compiler via the Xcode installation. Since valgrind still does not support Big Sur and the Apple version does not support Google Sanitizers I have to manually install llvm v11.1 via homebrew to leverage Google Sanitizers to have any memory leak detection tool enabled.
Unfortunately this causes some issues with conan and its integration with CMake and CLion, my IDE. Since my dependencies do not provide binaries for my architecture using clang instead of Apple-clang they have to built locally. Unfortunately conan and CMake error when invoking them with two contradictory error messages:

This is the output seen in the CMake output window of CLion. The first invocation has CMake think Apple-clang is my compiler while conan is configured to use the llvm version and on the second step (most likely invoked by conan_basic_setup in my CMakeLists.txt) the correct CMake compiler is chosen but Conan ends up without a profile hence a version mismatch.
In the CLion settings I have already overwritten the c++ compiler with the llvm v11.1 compiler:
What's the correct solution to properly configure both to use the llvm v11.1 compiler? I personally do not want to enable the CONAN_DISABLE_CHECK_COMPILER CMake variable as it is unclear which compiler will be used to compile dependencies in the end.
Previously posted questions only suggest intentionally using the higher version which is not what I want:
CMake Error: mismatch for the compiler version between your conan profile
Both packages I see in your log file, spdlog and fmt, are available as header only configuration.
So if these are your only dependencies, you can simply set the option to use them header only, and this will eliminate the problem since there is nothing to build for these packages.
One way doing so is adding the settings into the profile you use, into the option section, like that
[options]
fmt:header_only=True
spdlog:header_only=True
I was able to find a solution albeit by disabling the Conan integration first. With a clean build directory I went in there and had to invoke Conan manually as follows:
CC=clang CXX=clang++ conan install .. -pr=LLVM11Debug --build=missing
Afterwards it was possible run build with CMake and clang 11 configured in the UI of CLion. The issue was that the Conan integration plugin does not provide a direct way to set the compiler using the environment variables and it does not get the compiler from the Toolchain options in CLion.
I get this output when I run cmake in the CLion environment. When I run outside of CLion I get no warnings and everything works fine.
The really strange part about this is I specify clang and clang++ for the compiler, I do this in the CC and CXX environment variables as well as in the toolchain settings in CLion, but it is saying the g++ and gcc are having errors. However, no where in any of my config for CLion have I mentioned gcc or g++.
Where are these coming from and how can I fix it? It would be really nice to actually build this project from my IDE.
These issues started after the CLion 2017.3 update.

Ryan, it seems that CMake associated g++/gcc with specific targets in you project. I suspect that building will also fail. Could you check that?
If you are not able to resolve the problem, please file a ticket and we'll try to help.
I'm trying to use CMake to compile another library and it requires Boost.
I have installed both CMake and Boost using brew on OS X 10.10 Yosemite, but CMake refuses to find it. Boost is located in /usr/local/Cellar/boost/1.55.0_2
I've tried the following:
Setting -DBoost_DIR and -DBOOST_ROOT with the above path
Setting -DBoost_INCLUDE_DIR and -DBOOST_INCLUDEDIR with the above path + /include
Setting any and all of these options in the CMakeLists.txt file
Compiling Boost myself, and pointing the above vars to my own build
Trying out similar solutions to the same problem here, here, and here. The only answer that I found that mentioned brew on OS X was this one, and the same solution did not work for me.
Why is CMake blatantly ignoring my instructions? :(
Edit: CMake output from -DBoost_DEBUG=ON
I found a separate homebrew package of boost-python. With it installed, CMake does find Boost:
brew install boost-python
gives me

I was also having trouble compiling something with C++/Python/Boost/CMake (Specifically, I was trying to build https://github.com/mapillary/OpenSfM).
I was getting an error like this
Linking CXX shared library .../OpenSfM/opensfm/csfm.so

Inspired by the above comment, I tried to find this mythical "boost-python", but it didn't exist. Instead, I wound up using homebrew to reinstall normal boost with python.
brew install boost --with-python
That worked. CMake could now find boost and whatever python boost things it needed, and the compilation succeeded.
In my case upgrading both cmake and boost to their newest version solved the problem
brew upgrade boost cmake
