  • Problem: The variables REACT_ANDROID_DIR and BUILD_DIR might also contain backslashes if they are set on a Windows system. These backslashes need to be replaced to avoid similar issues.

  • Solution: Check if the script is running on Windows using if(CMAKE_HOST_WIN32). If it is, replace backslashes with forward slashes for these variables as well:

endif()

if (PROJECT_ROOT_DIR)

  • Problem: On Windows, backslashes () in file paths are often interpreted by CMake as escape characters, which can lead to invalid sequences like \S. CMake and many other tools can understand forward slashes (/) as directory separators, even on Windows.

  • Solution: Use string(REPLACE "\" "/" path "${path}") to convert all backslashes in the input_SRC file paths to forward slashes. This ensures CMake correctly interprets the paths without treating them as escape sequences.

add_library(${CMAKE_PROJECT_NAME} SHARED ${input_SRC})

target_include_directories(${CMAKE_PROJECT_NAME}
