Can't find `lz4` header when installing `roslz4` with pip on a Mac-CodePudding

I'm trying to install roslz4 on my Mac, and I get the following error.

      In file included from ros_comm/utilities/roslz4/src/_roslz4module.c:37:
      include/roslz4/lz4s.h:38:10: fatal error: 'lz4.h' file not found
      #include <lz4.h>
               ^~~~~~~
      1 error generated.
      error: command 'clang' failed with exit status 1
      [end of output]

To counter this, I installed lz4 with brew which ran successfully

> brew install lz4
