# CMake's Platform/DOS.cmake assumes OpenWatcom naming conventions (no prefix,
# .lib suffix). DJGPP uses standard Unix/GCC conventions for its system
# libraries (lib prefix, .a suffix — e.g. libm.a), so we override the platform
# defaults via CMAKE_USER_MAKE_RULES_OVERRIDE, which runs *after* the platform
# module has set its defaults, giving us the final say on these variables.
# The path must be cached because CMake re-parses the toolchain file during
# try_compile, where CMAKE_CURRENT_LIST_DIR may point elsewhere.

# CMake toolchain file for DJGPP. Usage:

# 1. Download and extract DGJPP
# 2. Add directory containing i586-pc-msdosdjgpp-gcc to PATH environment variable
# 3. When configuring your CMake project, specify the toolchain file like this:
#
# cmake -DCMAKE_TOOLCHAIN_FILE=path/to/i586-pc-msdosdjgpp.cmake ...
#
# specify the cross compiler
