Without this, checks with incompatible versions but the same library would
return true. Example:
dependency('zlib', version : '>=1.2')
dependency('zlib', version : '<1.0') # this will return the same dep again!
Example: https://github.com/mesonbuild/meson/issues/568
This simply sets the default version to be the same as the project version.
Useful for dependency version checks when using fallback subproject internal
dependencies.
This allows a project to use the same fallbacks dependency from the same
subproject multiple times in the same way that external dependencies can be.
Also change the format of the dependency identifier to ensure that fallback
checks with different dirname/varname aren't mistakenly reused. We now use
a tuple for this because the format is simpler to construct and it gives us the
same immutability guarantees as a string which is needed for using it as
a dictionary key.
The extra arguments are typically used to specified the location of
installed API references that gtk-doc can use to create cross links
for symbols.
Fixes#555
limits.h is a requirement of the C language and is available with all compilers
and platforms from the last two decades. If limits.h is not available, the
compiler only supports an ancient dialect of C and lots of other things will
break too.
Consolidate the C/C++ compiler sanity checks since the test code is almost
exactly the same, and then use that for the MSVC C/C++ compilers as well. All
these sanity checks had diverged because of the code duplication.
This also fixes an intermittent sanity check failure that I was seeing with
MSVC.
Note: The ObjC/C++ compilers can also probably use the same implementation.
The directory from where the source files are sought when producing a
coverage report in text or XML format should not be the build directory
but the source directory instead.
Object files from a custom_target are like external objects and must be
added to the project.
Object files from a generator are automatically used by MSBuild, since they
are part of the CustomBuildStep and thus part of the same project as the
current build target.
