Tests fail to build if clangmetatool is integrated using CMake’s FetchContent #81

Open rknuus opened 6 days ago

rknuus commented 6 days ago

While the project builds without error when building it stand-alone, the tests fail to build if clangmetatool is integrated as follows into a CMake project:

include(FetchContent)
FetchContent_Declare(
  clangmetatool
  GIT_REPOSITORY https://github.com/bloomberg/clangmetatool.git
  GIT_TAG        0.21.7
)
FetchContent_MakeAvailable(clangmetatool)

An example of a build failure message is:
