Fix issues with build system and MacOS

hhslepicka commented 4 years ago

Summary

This PR addresses issues that were found while trying to install SRW at my computer. Here are the issues that this Pull Request addresses:

../src/core/srsysuti.cpp:25:10: fatal error: 'sys/sysinfo.h' file not found This is due to -DLINUX being hardcoded at this file: cpp/gcc/Makefile
fftw setup was wrong. It was missing the download part for the FFTW tarballs It was also inconsistent between the fftw2 and fftw3.
make clean is not really clean It was leaving the libfftw.a at ext_lib

After the fixes above I can simply do:

I noticed the following that I would like to bring to your attention:

many products are being version controlled and they can lead to bad linking. E.g: env/work/srw_python/srwlpy.so ext_lib/GlutViewer.lib ext_lib/GlutViewer64.lib ext_lib/fftw3_64.lib ext_lib/fftw3f_64.lib ext_lib/fftw64_f.lib ext_lib/fftw_f.lib ext_lib/glut32.lib ext_lib/glut64.lib ext_lib/libf2c.a ext_lib/libf2c.lib ext_lib/libfftw3_mac.a ext_lib/libfftw3f_mac.a ext_lib/libfftw_f_i686.a ext_lib/libfftw_f_x86_64.a ext_lib/libfftw_mac.a ext_lib/libfftwf_mac.a ext_lib/libpng.lib ext_lib/libpng64.lib ext_lib/zlib.lib ext_lib/zlib64.lib
product SRW Library should never be on version control as it is specific to my compiler and system: env/work/srw_python/srwlpy.so and can lead to issues if not cleaned up properly.

Attn. @mrakitin I think that now your Conda recipe will build again for MacOS and Windows.

Thanks for the update, @hhslepicka. How would Makefile be used on Windows? mingw?
