#=== CREATING COMPILING DATABASE ===#
# Currently CMake (since 2.8.5) supports generation of compilation databases
# for Unix Makefile builds (Ninja builds in the works) with the option
# CMAKE_EXPORT_COMPILE_COMMANDS.

#=== FINDING PACKAGES ===#

# # Locate TinyXml2 package (library)
# # find_package(TinyXml2 REQUIRED)
# # include_directories(${TinyXML2_INCLUDE_DIRS})

# TinyXML2 is not a module package, therefore cannot be found with find_package() command.
# Set those manually, for now.
set( TinyXML2_INCLUDE_DIRS "tinyxml2" )
set( TinyXML2_LIB_DIRS "tinyxml2" )
set( TinyXML2_LIBRARIES "tinyxml2" )

# Set "manually" paths that need to be considered while compiling/linking
