I'm new to CMake to I'm not sure what I'm doing.
I'm using poppler as a library via CMake for my application. I've imported it as a submodule. If I include popper in my top-level CMake file using add_subdirectory(...), it gets the following errors [cmake] CMake Error at external/poppler/CMakeLists.txt:7 (include): [cmake] include could not find requested file: [cmake] [cmake] PopplerDefaults [cmake] [cmake] [cmake] CMake Error at external/poppler/CMakeLists.txt:8 (include): This is most likely because the CMAKE_MODULE_PATH is incorrect. After some digging, it looks like poppler is setting the module path instead of appending to it. https://gitlab.freedesktop.org/poppler/poppler/-/blob/master/CMakeLists.txt#L5 So I can't really override it. My (probably overly complicated) setup is here, which the poppler line commented out. https://github.com/bdurrani/cmake-test/blob/master/CMakeLists.txt#L69 This works fine if I run cmake from within the poppler folder. Are there any examples of consuming the poppler build from another CMake project? I did tweak the CMake file to use list APPEND​ instead of set, but that triggers other path issues ``` [cmake] CMake Error at external/poppler/utils/CMakeLists.txt:39 (add_executable): [cmake] Cannot find source file: [cmake] [cmake] /home/bdurrani/deletethis/cmake-test/poppler/CairoFontEngine.cc [cmake] [cmake] Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm .h [cmake] .hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90 .f95 .f03 .hip .ispc ``` Thanks for your help!
