FindChrome.cmake

# FindChrome.cmake
# Searches for Chrome and sets up a few helpful macros.
#
# Outputs:
#  CHROME_FOUND - True if Chrome was found
#  CHROME_INCLUDE_DIRS - List of include directories for Chrome headers
#  CHROME_CFLAGS - C flags to pass to compiler for Chrome
#  CHROME_LIBRARY_DIRS - List of library directories for Chrome
#  CHROME_LDFLAGS - flags to pass to the linker for Chrome
#
# Output Macros:
#  On Mac:
#
#  ADD_CHROME_APP - Adds a Chrome .app target for Mac by generating the
#                   appropriate app structure and symlinking in another target
#                   as the actual executable
#   Paramters:
#    APP - the name of the app to link to, must be a file or existing target
#    LINKS - additional binaries to link into the .app; this almost certainly
#            includes the renderer binary
#    COPY - additional files to copy into the .app
#
#  On Linux:
#  ADD_CHROME_SYMLINK_TARGET - Adds a target which adds symlinks to the
#                              to the necessary Chrome libraries and resources
#   Parameters: None
