making the build between Simgear and Flightgear consistent.
- Fix an issue with lib/lib64 path between CentOS/RedHat distributions
and Debian derived distributions.
- Fix a compilation issue with HLA in the Flightgear code.
Refactor to break circular references.
New custom target generates the resource files.
FGFS and Test_Suite targets declare a dependency to the generated files.
This is necessary on macOS where DBus is typically installed using
Homebrew, and hence we need additional linker flags to find the
library. Using the PkgConfig::DBUS imported target handles all this
transparently, but then we need to define an imported target for
Windows to work.
- When FGDATA_SRC_DIR isn't explicitly set by the user, set it to
${PROJECT_SOURCE_DIR}/../fgdata if this is a directory.
- When TRANSLATIONS_SRC_DIR isn't explicitly set by the user, look for
translations in ${FGDATA_SRC_DIR}/Translations instead of
${PROJECT_SOURCE_DIR}/../fgdata/Translations (i.e., honor the setting
of FGDATA_SRC_DIR for the sake of translation lookup).
This fixes the problem explained in [1] and [2].

This allows the sources and headers in src/Main/ to be used by other targets.
They are grouped into the new "Main" flightgear component via the macro in the
FlightGearComponent CMake module. The bootstrap.cxx file with its main function
has been separated out into a separate variable MAIN_SOURCE for use by the fgfs
binary.
All these files have therefore been removed from the test_suite CMakeLists.txt
file, as they are added via FG_SOURCES and FG_HEADERS. The MSVC grouping code
also does not need to deal with the now deleted separate SOURCE and HEADER
variables for these files.
This is for simplifying the main src/Main/CMakeLists.txt file and allowing the
code to be shared with the test suite.
The generated source and header files have also been removed from the main
source list and placed in the CMake module as the global variables
EMBEDDED_RESOURCE_SOURCES and EMBEDDED_RESOURCE_HEADERS.
This includes the basic CMake infrastructure for building and executing the test
suite. Four test categories have been added - unit, system/functional, GUI, and
simgear unit tests. The test suite is run by typing 'make test_suite'.
All of the fgfs sources are included in the new run_test_suite executable,
excluding the bootstrap routine and its main() function. The test suite
currently consists of a single dummy unit test for the NasalSys subsystem, and a
single demonstration simgear/props unit test.
