Flibcpp example app

Example standalone application that uses Flibcpp (and nothing else, not even a C++ compiler).

Build with automatically downloaded flibcpp

1. Clone this repository: git clone https://github.com/swig-fortran/flibcpp-example-app
2. Create a build directory: mkdir build && cd build
3. Configure, build, and run: cmake ../flibcpp-example-app && make && ./example

Build with externally installed flibcpp

Clone this repository and create a build directory as above. Provide your existing flibcpp's installation prefix to CMake using the CMAKE_PREFIX_PATH environment variable, and disable the BUILDIN_FLIBCPP option on the configuration line:

$ CMAKE_PREFIX_PATH=/usr/local/myflibcpp \
> cmake -DBUILDIN_FLIBCPP=OFF ../flibcpp-example-app

Then make and run as before.
