There's no way to know that loading an arbitrary module doesn't pull in
extra dependent modules so the test case asserting that exactly one module
was loaded isn't valid.
pkg-config's .pc files can sometimes provide libraries that are visible to
the linker but not present in CMake's known search paths. In the case
where CMake can find some, but not all of the library dependencies
provided in a .pc file, this allows them to be passed through as "-lfoo"
when the full path can't be found.
This also removes the test failure cases that occured because of this
scenario and adjsuts the remaining tests to account for not-found
libraries
The new `AUTOMOC_PATH_PREFIX` boolean target property enables automatic
generation of the path prefix `-p` option for `moc`.
`AUTOMOC_PATH_PREFIX` is initialized from the variable
`CMAKE_AUTOMOC_PATH_PREFIX`, which is ON by default.
When `AUTOMOC_PATH_PREFIX` is enabled, CMake tests if a `moc`ed header file is
in one of the include directories. If so, then the `-p` option, with the
relative path of the header parent directory to the respective include
directory, is added to the `moc` command. If the header file is not in an
include directory, the `-p` option is omitted.
Closes: #18815 "AUTOMOC: generated files include full relative path,
breaking certain reproducible builds"
This introduces the `cmQtAutoGenerator::MessagePath` method, that abbreviates
paths by placing a
- "SRC:" prefix in place of the project source directory
- "BIN:" prefix in place of the project binary directory
The method is used in `AUTO{MOC,UIC,RCC}` when paths are displayed in
messages. This makes the messages generated by `AUTO{MOC,UIC,RCC}` shorter
and improves their readability.
This splits the `JobEvalCacheT` job into separate `JobEvalCacheMocT` and
`JobEvalCacheUicT` classes, that run concurrently.
The `JobEvalCache*T::FindIncluded*` methods are overhauled to store probed
directoriy names only if probing fails. Warning messages are refactored
to show the file name and the probed directories instead of all probed file
paths. This is easier to read.
By splitting `JobProbeDepsT` into two independent `JobProbeDepsMocT`,
`JobProbeDepsUicT`, the moc and uic job generation will happen concurrently.
This should improve the execution speed, when both AUTOMOC and AUTOUIC are
enabled.
Parent directory names for moc and uic output files are are collected in
a `std::unordered_set<std::string>` and get created in a batch.
Beforehand we tried to create the parent directory for each output file.
This led to duplications of `MakeDirectory` calls when there were multiple
output files in the same directory (which is the case usually).
This removes code that sorts include directories for `AUTOMOC` according to
`CMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE`. This is possible because the
included directories passed to `AUTOMOC` are already sorted, also with
respect to `CMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE`.
