When using cmath in Mac OS Catalina along with PCL Library I have to do the change proposed in https://stackoverflow.com/a/61519060/6131111
2. Using #include</Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/math.h> instead of <math.h> in /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/cmath
in order to avoid the following errors:

If I change this import then I can run PCL, but now I cannot run any normal script that I develop that imports cmath.h as I get the following errors:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/math.h:760:41: error: no member named 'fabsf' in the global namespace; did you mean 'labs'?

Then I have to contantly change the math.h import in /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/cmath depending on what I am working. Do you have any solution?
