Instead of a bool. The latter will result in de-initing leaving the
library unable to init again, which works out for the cli, but is
problematic for other consumers (meson++ and muon).
v2: - Add docs that the functions are not thread safe
This allows others using libpkgconf as a dependency to do use this as a
subproject. They can write something like:
```meson
dependency('libpkgconf', fallback : ['libpkgconf', 'dep_libpkgconf'])
```
Then install a wrap file for libpkgconf and build it as part of their
project.
Projects using PKG_CHECK_MODULES wants to add dependency versions to
their binaries. Currently, the projects have to resolve dependency
versions themselves when using pkgconf.
With this patch PKG_CHECK_MODULES now defines a $PKG_VERSION variable
that represents `--modversion`.
Currently the indentation in PKG_CHECK_MODULES is a mix och tabs and
spaces which makes it hard to read. This patch unifies the indentation
in the function to spaces.
A bunch of CMake developers, who apparently did not comprehend the previous
compatibility promise statement, decided to passive-aggressively demand we fix
their non-bug anyway.
Clarify in more detail what level of pkg-config compatibility we provide, and
mention that such passive-aggressive behaviour is considered a CoC violation.
Fixes#228.
Prior to this commit, the code path responsible for prefix redefinition
(motivated by --define-prefix or otherwise) was visited more than
once, specifically since the check ignored pkg->owner->prefix_varname.
The current approach was to parse the .pc and, detect the prefix, throw
everything together and at the end replace all \ with / to not produce invalid
escape sequences.
This has the problem that escaping in .pc files is ignored and no longer
possible. Also in case the prefix path has a space in it the result would be
invalid because of missing escaping.
This changes the following things:
* We no longer normalize values at the end. Instead we assume .pc files use "/"
as a directory separator or "\\", same format as under Unix. "\" alone no
longer works. This shouldn't be a problem since most build tools produce .pc
files with "/" like meson, cmake, autotools.
* When injecting the prefix at runtime we convert the prefix to use "/" and
escape spaces so that in combination with the .pc content the result is a
valid escaped path value again.
This patch has been used in MSYS2 for some months now.
