ASM: might be:
https://en.cppreference.com/w/c/atomic
https://code.woboq.org/linux/linux/arch/x86/include/asm/atomic.h.html
Because by use of option "-latomic" and "<wx/atomic.h>", so, we have to find wxWidget.
We can not find like the blow:
$ yum update

At least, we put X11 library to the :
FindX11.cmake
/opt/graphics/OpenGL/include
/opt/X11/include
)
set(X11_LIB_SEARCH_PATH
/usr/pkg/xorg/lib
/usr/X11R6/lib
/usr/X11R7/lib
/usr/openwin/lib
/opt/X11/lib
#ADD 20200921
/usr/lib/X11
)
we understand the reason why we can not cmake is we can not find "X.h", so installed.
$ yum search X11
$ yum install libX11-devel.i686
$ find / -name X.h
/usr/include/X11/X.h

in the small project, we should write once about pthread which is "p-thread".
Program thread:
---
(20200922: work: audacity: )
We coud find HAVE_PTHREAD in the tif_config.h
./src/tiff/libtiff/tif_config.h:#define HAVE_PTHREAD 1
so, we understand "HAVE_PTHREAD" if the above is only keyword "HAVE_PTHREAD".
so, in the CmakeCache.txt, "CMAKE_" is prefix and "_H" is a header which they found.
(20200922: tutorial)
We set just only #define.
---
(20200922: simple case)
We could build with inclusion in the simple case.
We ignore "#define HAVE_PTHREAD 1" in tiff library.

There is no keyword "HAVE_PTHREAD" CMakeLists.txt in audacity and in the tiff.
We must rebuild as same as first.
