Package: libpoco-dev
Severity: important
X-Debbugs-Cc: [email protected]
Dear Maintainer,
I am attempting to use libpoco-dev cmake files on bullseye, but the
problem encountered dates back to the addition of the cmake files to
the libpoco-dev package as part of
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=880614
The CMakeLists.txt snippet which should work is:
find_package(Poco COMPONENTS Foundation REQUIRED)
However that looks for "Poco" cmake files and fails.
This first problem is raised upstream as
https://github.com/pocoproject/poco/issues/3244
I can workaround this by doing
# ln -s /usr/lib/x86_64-linux-gnu/cmake/cmake/Poco/ /usr/lib/cmake/
Then we encounter the following error:
CMake Error at /usr/share/cmake-3.18/Modules/CMakeFindDependencyMacro.cmake:47
(find_package):
By not providing "FindPCRE.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "PCRE", but
CMake did not find one.
Could not find a package configuration file provided by "PCRE" with any of
the following names:
PCREConfig.cmake
pcre-config.cmake
Add the installation prefix of "PCRE" to CMAKE_PREFIX_PATH or set
"PCRE_DIR" to a directory containing one of the above files. If "PCRE"
provides a separate development package or SDK, be sure it has been
installed.
Call Stack (most recent call first):
/usr/lib/x86_64-linux-gnu/cmake/cmake/Poco/PocoFoundationConfig.cmake:5
(find_dependency)
/usr/lib/x86_64-linux-gnu/cmake/cmake/Poco/PocoConfig.cmake:29 (find_package)
CMakeLists.txt:48 (find_package)
This is because libpcre2-dev and libpcre3-dev dont include any of those
mentioned files (FindPCRE.cmake, PCREConfig.cmake, or
pcre-config.cmake).
Note pcre2 does has a pcre2-config.cmake.in file which presumably
is used to generate a pcre2-config.cmake .
https://sources.debian.org/src/pcre2/10.39-3/cmake/
This wont suffice, as it doesnt provide cmake library `Pcre::Pcre`
which is needed by Poco.
However I can workaround this by adding the followinfg to /usr/lib/cmake/Poco/
as set up previously.
https://github.com/pocoproject/poco/blob/master/cmake/FindPCRE.cmake
Note the contents of that file mention `Pcre::Pcre`.
Worth noting vcpkg goes about fixing this a different way, by creating
their own unofficial-pcre-config.cmake at
https://github.com/ddc7451/vcpkg/tree/5746100fdc746523dd6cb1bac2cd1c0a50e0c253/ports/pcre
and then patching poco to look for unofficial::pcre::pcre
