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

Do I need to add the location of lz4 headers to an environment variable? How can I get pip to find the header?
After doing brew install lz4 the following (from this SO post by rgov) worked for me without the need of any source code changes:
CFLAGS="-I$(brew --prefix lz4)/include" \
LDFLAGS="-L$(brew --prefix lz4)/lib" \
pip install roslz4 --extra-index-url https://rospypi.github.io/simple/
