# Cygwin and pkg-config
$ env 'PKG_CONFIG_PATH="Y:\source\dkml\build\pkg\bump\msys64\clang64\lib\pkgconfig"' pkg-config --cflags libffi
Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'to the PKG_CONFIG_PATH environment variablePackage 'libffi', required by 'virtual:world', not found# MSYS2 and pkgconf$ env 'PKG_CONFIG_PATH="Y:\source\dkml\build\pkg\bump\msys64\clang64\lib\pkgconfig"' pkgconf --cflags libffi-IZ:/msys64/clang64/bin/../include
Conclusion: adding double-quotes breaks both pkg-config and pkgconf
