Subject: [PATCH] Fix installation of header files with cmake (#1186)

* Fix installation of header files with cmake

Install only the required header files, with openblas_config.h preprocessed like in Makefile.install
Fixes #1184

* Update CMakeLists.txt

Escape remaining semicolons in awk argument list (to get it working on Windows as well)

* Update CMakeLists.txt

* Update CMakeLists.txt

* Update CMakeLists.txt

* Update CMakeLists.txt

* Update CMakeLists.txt

* Add files via upload

* Update CMakeLists.txt

* Update CMakeLists.txt

* Update CMakeLists.txt

* Update CMakeLists.txt

* Use C utility instead of awk for header generation in cmake builds

* Update CMakeLists.txt

* Fix generation and installation of header files

Generate openblas_config.h and f77blas.h with same contents as in plain Makefile builds and install only the public header files
