My private C++ library (C++ headers) for many projects.
Put it to a directory ( example 'prilib' ).
Then:
mkdir build
cmake ..
make
Then, put libprilib.a to your project, and get it referred.
gcc -Lprilib/include -lprilib XXXX
Or use CMake, ...
If you want to change the name of namespace PriLib, you can use cmake .. -DPRILIB=XXXX .
If you want to a header file which include all headers, you can use 'prilib.h' (It was made by 'create-header.py').
