Build failure when compiling as a CMake subdirectory with MinGW. #990

Closed Domssson closed 7 months ago

Domssson commented 7 months ago

If the library code is added as a subdirectory in a CMake project and then cross-compiled with MinGW on Linux, the build fails. During linking, the OpenAL32.def file is created just inside the build directory, but then it's expected to be in build/openal-soft by sed command. If one copies the OpenAL32.def file to the correct directory and runs cmake --build . again, the build process proceeds as it should.

Here's a very simple CMake script that triggers this behaviour, assuming that the library is in the openal-soft directory in the project:

cmake_minimum_required(VERSION 3.12)

project(TestProject)

add_subdirectory(openal-soft)

The solution to the problem would be to generate the OpenAL32.def in the correct directory when linking.

Here is the log from CMake:
