Raw Normal View History

Simplify CMake per-source license notices Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

Remove trailing whitespace from most CMake and C/C++ code Our Git commit hooks disallow modification or addition of lines with trailing whitespace. Wipe out all remnants of trailing whitespace everywhere except third-party code. Run the following shell code: git ls-files -z -- \ bootstrap doxygen.config '*.readme' \ '*.c' '*.cmake' '*.cpp' '*.cxx' \ '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \ '*.mm' '*.pike' '*.py' '*.txt' '*.vim' | egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' | egrep -z -v '^(Modules/CPack\..*\.in)' | xargs -0 sed -i 's/ \+$//'

find_path(SDL_IMAGE_INCLUDE_DIR SDL_image.h
ENH: Cleanup Find* modules with new HINTS feature - The find_* commands now provide a HINTS option. - The option specifies paths to be preferred over the system paths. - Many Find* modules were using two find calls with NO_DEFAULT_PATH to approximate the behavior, but that blocked users from overriding things with CMAKE_PREFIX_PATH. - This commit uses the HINTS feature to get desired behavior in only one find command call.
2008-06-10 00:04:06 +04:00
HINTS
use the find_* functions ENV parameter Instead of directly passing $ENV{SOMEVAR} to a find_* call pass in ENV SOMEVAR. This will make sure the paths will get correctly handled through different platforms, especially on Windows. Also fixes one place where paths with windows delimiters (\) were hardcoded to use forward slashes.

FindSDL: Make FindSDL_*.cmake path suffixes consistent with main module Add the 'SDL' path suffix to the FindSDL_*.cmake modules. Add a comment explaining the purpose of suffixes as in commit v3.0.0-rc1~540^2 (FindSDL: Add path suffixes for <prefix>/include/..., 2013-10-08).

PATH_SUFFIXES SDL
# path suffixes to search inside ENV{SDLDIR}
include/SDL include/SDL12 include/SDL11 include
BUG: Fixed modules to set FOO_FOUND when both headers and libraries are found. BUG: FindSDL now has flag it responds to so it will not find/link against SDLmain. This is required to build libraries instead of applications since they don't have main(). ENH: All modules have a predictable search order, where environmental variables are searched before system paths. This is designed to make automation easier for those that need to automatically build projects without intervention but may be using alternative install locations for isolated testing. ENH: New modules for OpenSceneGraph, Freetype, GDAL, Lua, QuickTime, GIFLIB, Producer, OpenThreads. STYLE: Added documentation explaining peculuar SDL_LIBRARY_TEMP variable in SDL module when library find is incomplete.
