# This file adds support for the C# language to cmake.
#
# It adds the following functions:
#
# csharp_add_executable (<name> <source files> [UNSAFE] [WINEXE] [REFERENCES <references>]
# [COMPILE_FLAGS <flags to be passed to the compiler>]
# [COMPILE_DEFINITIONS <additional definitions>] )
#
# csharp_add_library (<name> <source files> [UNSAFE] [REFERENCES <references>]
# [COMPILE_FLAGS <flags to be passed to the compiler>]
# [COMPILE_DEFINITIONS <additional definitions>] )
#
# install_assembly (<target name> [NO_GAC] DESTINATION <assembly destination directory>
# [PACKAGE <package name>] )
# The assembly destination directory is only used if we compile with Visual C# and thus can't use gacutil.
# If a package is specified and a file called <target>.pc.cmake exists in the current source directory,
# this function will configure the template file. All occurences of @assembly@ will be replaced with
# the path to the assembly. The resulting <target>.pc file will be installed to
# <CMAKE_INSTALL_PREFIX>/lib/pkgconfig/ . If you want to have a different basename for the template file,
# set the 'pkg-config_template_basename' property of the target with set_property.
#
# Example:
# ------------------------------
# cmake code:
# ------------------------------
# csharp_add_library(foo foo.cs)
# install_assembly(foo DESTINATION lib)
#
# ------------------------------
# contents of foo.pc.cmake file:
# ------------------------------
# Name: Foo
# Description: Foo library
