# In this directory, a number of different processes are managed:
#
# 1) PNG files are created from SVG files for each icon theme and needed bitmap resolution
# 2) An images.tar.gz file is created from all the PNG files
# Step 2) is universal and is done for any builder, whereas step 1) is
# optional and depend on MAINTAIN_PNGS being defined in CMake. The reason we
# can skip 1) is that the *.PNG files are part of the source tree so
# do not need to rebuilt by a typical builder. However, because the *.PNG files
# are part of the source tree, and subject to version control, they should be built
# only when needed, otherwise this results in a diff for the version control system.
# Therefore step 1) is driven by CMake (if MAINTAIN_PNGS) which gives
# us conditional *.PNG building based on an edit to the respective *.SVG file.
# If MAINTAIN_PNGS is not defined, then you are a normal builder and no special
# tools are required. If MAINTAIN_PNGS is defined, then you are a PNG maintainer
# and will need the following tools findable in your PATH:
#
# 1) inkscape - command line mode is used, must be on your PATH
# 2) pngcrush - this program must be on your PATH
#
# lower case is used for local variables, uppercase for global variables
option( MAINTAIN_PNGS
"Set to true if you are a PNG maintainer and have the required tools given in the resources/bitmaps_png/CMakeLists.txt file (default OFF)."
