@ -234,6 +234,7 @@ Things you might need to change in `CMakeLists.txt` files:
1. gba-sprite-engine assumes your GBA cross-compiler is in your `$PATH`. If it's not, add an absolute path to `SET(CMAKE_C_COMPILER arm-none-eabi-gcc)` etc.
2. gba-sprite-engine assumes your Google Test Library is compiled and in your `$GTEST_DIR` path. If not, add an absolute path to: `SET(GTEST_LIBRARY "/Users/jefklak/CLionProjects/googletest-release-1.8.0/googletest")`. The linker searches for 'ligbtest.a' and 'liggtest_main.a' - if you're on Linux it'll likely be a .so extension.
3. Some Linux distributions seem to miss the default link to `pthread` that should be added manually in that case. When you see errors like "undefined reference to 'pthread_setspecific'" while linking Google Test, change target_link_libraries in the CMakeLists.txt file of the subdir test to: `target_link_libraries(unittest ${GTEST_LIBRARY}/build/libgtest.a ${GTEST_LIBRARY}/build/libgtest_main.a pthread)`
