I have this in my main CMakeLists.txt:

I am writing a script that will compile a few hundred applications using CMAKE. These applications use various compilers for embedded systems and each has it’s own build instructions. Usually we use compilers on shared network drive, but in order to speed things up I want to check which compiler should be used, cache it locally and override compiler settings via command line.

I want to set a compilation option -DVAR=xxx. I know that I can do this with target_compile_options but my issue is that the value xxx has to be dynamically generated and is only available as the content of a txt file.

if(“$<CONFIG:Debug>”) target_compile_definitions(Geodesic-RayTracer PRIVATE TESTING_ENABLED) endif() #target_compile_definitions(Geodesic-RayTracer PRIVATE TESTING_ENABLED) I have the above in my CMakeLists.txt for my project. If I uncomment the line below endif() my code has TESTING_ENABLED set. So I know that part is correct. However I only want to set it on Debug builds. The C++ pattern I’m trying to follow looks […]

I’m building a C++ project with CMakeLists.txt, that depends on some library, which is built in the build-process. I’ve used:
add_subdirectory(/path/to/some_lib)
that contains another CMakeLists.txt, that builds that library. In order to link I call:
target_link_libraries(${target} some_lib_name)
My question is:
how am I supposed to know what “some_lib_name” to use in target_link_libraries?

I would like to capture the output of CMake testing. Using Xcode, one can find a file named LastTest which includes most of what I want. But it seems to not include build/link failures. If a test fails to compile, nothing at all appears in the LastTest file.

I have an app, an interface library and plugins.
I define the targets in the main lists file.
Plugins are included using add_subdirectory(plugins).
I want plugins to be able to use find_package in the build and install tree.
I exported targets like this

I’ve seen a couple of posts suggesting that it’s possible to use to break long lines in CMakeLists.txt. But in my world it appears not to be true. Here’s my CMakeLists.txt:

I am able to build a simple application using a MakeFile with the contents…

I have been going through find_package syntax and it says this about version here https://cmake.org/cmake/help/latest/command/find_package.html :
