This commit enables CMake to generate a flatbuffers.pc file on install.
pkg-config eases the utilization of software libraries by enabling the
developers of a library to define how the library should be used.
It can be used as a tool by build systems to find and manage dependencies,
this is notably the default Meson behavior and optionally used by CMake.
This change is for fix warning:
```
CMake Warning (dev) at /home/aoleksy/share/cmake-3.17/Modules/FindPackageHandleStandardArgs.cmake:272 (message):
The package name passed to `find_package_handle_standard_args`
(flatbuffers) does not match the name of the calling package (FlatBuffers).
This can lead to problems in calling code that expects `find_package`
result variables (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
FindFlatBuffers.cmake:33 (find_package_handle_standard_args)
CMakeLists.txt:6 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
```
This option was in an earlier revision of flatbuffers_generate_headers
but was lost while refactoring by mistake. We have it as a function
argument rather than one of the optional flags so that we can use it to
inform the rule where to place the generated headers, so that the file
location matches the prefix that will be added to the filenames in the
generated files.
Also fixed some of the documentation in the file.
flatbuffers_generate_headers is a function that can be used to generate Flatbuffers headers and binary headers. It uses named argument flags to wrap all the flags relevant to C++ header generation that flatc uses. It generates an interface library that can be added as a dependency of other targets.
flatbuffers_generate_binary_files is a function that can be used to generate Flatbuffers binaries. It uses named argument flags to wrap all the flags relevant to C++ binary generation from JSON file that flatc uses. It generates an interface library that can be added as a dependency of other targets.
* Add RPM packaging support
Using the existing PackageDebian as template add support for
generating an rpm with the package target.
* Restore debian package target
Also add an option to advertise the fact.
* Update package description
C-n-p from README.md
* Update rpm package maintainer
added bii-travis.sh and readme.md files; added build status section with travis and biicode build
systems
