error: command 'gcc' failed with exit status 1

I tried to pip install pycodec2 after building codec2 from source. I got some error. This is how I installed:

First I installed codec2:

!sudo yum -y install cmake3
!git clone https://github.com/aviasd/codec2
!cd codec2 ; mkdir build_linux ; cd build_linux ; cmake3 .. ; make

The git repo I used is https://github.com/aviasd/codec2.
It is the same as the original repo but I removed the -no-pie option (see comparison).

It worked:

Then, I tried to install pycodec2:

!pip install pycodec2

I got this error:

I tried to put some environment variables in place like I saw in here and here:

%env CPATH=.

%env CPATH=/home/ec2-user/SageMaker/codec2/src

With no success.
I tried to add /home/ec2-user/SageMaker/codec2/src to LD_LIBRARY_PATH, no success either.

I think the problem is:

The file codec2.h is not inside codec2 directory.
It is inside codec2/src directory.
This is the full path: /home/ec2-user/SageMaker/codec2/src/codec2.h.

How can I make it work?
Thank you,
