[CMake] Building a tool immediately so it can be used later in same CMake run

All, I originally planned to ask this question directly on this mailing list, but it got a bit more involved, so I posted it to stackoverflow instead. I'm interested if anyone can shed some more authoritative light on the proposed method for the following question: http://stackoverflow.com/q/3608

Re: [CMake] Creating a list of link directories from a variable

Hi, If the library is a shared object, try to NOT use all those libraries. If they are used in the library but are not part of its public API, you most likely don't need to link them. If you have no missing symbols when linking, you can avoid overlinking you program. If this is a static librar

[CMake] Creating a list of link directories from a variable

Hello I am trying to compile a program with a library that provides a bash script to generate the dependencies, libraries and the link directories for the Makefile. I want to generate a CMakeLists.txt that can handle these dependencies from that library. I have been able to come up with regexp

Re: [CMake] Mixing up project language settings?

If the new C++ components are built optionally, I would use enable_language(CXX): https://cmake.org/cmake/help/latest/command/enable_language.html Otherwise, if the project will always need C++ support from now on, amend the project() statement. In this case it doesn't matter whether you add CXX o

Re: [CMake] using cmake to link header files: file could be found, is included, but build error when using nmake.

Hi Karel, I've noticed a few points where you could start looking for a solution: * You're mentioning that CMake warns about some linking stuff, but the compiler error is one about including a header file. Libraries and headers are fundamentally different objects: header files are used by the com
