Using environment variable is sometimes more convenient when you do not control the build scripts   process  For C includes use C INCLUDE PATH  For C   includes use CPLUS INCLUDE PATH  See this link for other gcc environment variables  Example usage in MacOS   Linux    pip install  will automatically run  gcc  using parameters   specified in the  asyncpg  package  that I do not control   C INCLUDE PATH  home scott  pyenv versions 3 7 9 include python3 7m pip install asyncpg  Example usage in Windows set C INCLUDE PATH  quot C  Users Scott  pyenv versions 3 7 9 include python3 7m quot   pip install asyncpg    clear the environment variable so it doesn t affect other builds set C INCLUDE PATH
