I'm going crazy to link OpenSSL with project that I'm implementing using MinGW and setting the project with CMake Gui.
It basically fails to link properly with the OpenSSL libraries.
Here's my CMake settings -> https://ibb.co/5Y0TB5Y.
Here there are the CMakeLists.txt that I used in my project:

I really don't understand what I'm doing wrong. I've tried to use both the openssl *.a and the *.lib libraries and I had the same result. My OpenSSL version is 1.1.0k and Boost is 1.68.
I also tried to set CMAKE_CXX_FLAGS = -lssl -lcrypto but the output says that ld.exe can't find the libraries. Any help?

Before anything, I just want to say I am very new to CMAKE, almost never used it but now forced to...
I am trying to include snmp features in a previous project, using Net-SNMP library. But first, I wrote a minimalistic code just to test my functions. According to the library tutorial, this is how I must compile the code:
First, I must create object file:
gcc -I. `net-snmp-config --cflags` -c -o tfsnmpset.o tfsnmpset.c
Then, I must generate the executable:
gcc -o tfsnmpset tfsnmpset.o `net-snmp-config --libs`
By doing this, the program compiles perfectly and everything is fine.
Now the project in which I want to incorporate that piece of code uses CMakeLists.txt to generate its makefile.
My question is, how do I include the following flags in my CMakeLists.txt?
When creating object files: `net-snmp-config --cflags`
When generating executable: `net-snmp-config --libs`
I actually tried to build a library out of my code that uses Net-SNMP that I could just use in my main project:
cmake_minimum_required(VERSION 3.12)
project(snmp_daemon C)
set(CMAKE_C_STANDARD 99)
SET(CMAKE_C_COMPILER /usr/bin/gcc)

I got another problem after changing the cmakelists

You should pass boost libraries to the target_link_libraries command. The smallest change to your file will be as follows:
target_link_libraries(qttest ${QT_LIBRARIES} ${LIBS})
But since you are using find_package for Boost and you do not actually use your LIBS variable anywhere, you should stick with something like this:
find_package(Boost COMPONENTS system REQUIRED)
...
target_link_libraries(qttest ${QT_LIBRARIES} ${OpenCV_LIBS} ${Boost_LIBRARIES})
And remove LIBS altogether.

You need to link pthread / libpthread. Depending on the linker, this might be done automatically, but not in your case.
I'm getting this error when i try to run "pcl pcl_write.cpp". The cpp file is just a test program to check if pcl is working. (Also, alias pcl = ~/.compile.sh ).
