LeechCraft

Additionally, with USE_QT5=ON, it still looks for qmake-qt4:

-- Looking for Q_WS_MAC - not found
-- Found Qt4: /usr/local/bin/qmake-qt4 (found version "4.8.7")
CMake Error at plugins/summary/CMakeLists.txt:15 (find_package):
By not providing "FindLeechCraft.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"LeechCraft", but CMake did not find one.

Could not find a package configuration file provided by "LeechCraft" with
  any of the following names:

LeechCraftConfig.cmake
    leechcraft-config.cmake

Add the installation prefix of "LeechCraft" to CMAKE_PREFIX_PATH or set
  "LeechCraft_DIR" to a directory containing one of the above files.  If
  "LeechCraft" provides a separate development package or SDK, be sure it has
  been installed.

Which version is that?

HEAD only supports Qt5 for quite some time now. I believe the dependency on QtDeclarative has also been dropped, but I'll double-check.

0.6.70

I am trying to update the FreeBSD port. I can't use the head, it has to be in a tarball.

That's >4 years old now, IIRC it doesn't support Qt5 at all.

Would a weekly snapshot work? Say, https://dist.leechcraft.org/LeechCraft/0.6.75/leechcraft-0.6.70-12062-gcc93e7b776.tar.xz

BTW the FreeBSD port might be really outdated. In any event, the Gentoo ebuilds might help to figure out the correct dependencies and their versions: https://github.com/gentoo/gentoo/tree/master/app-leechcraft

I'm trying to update the port.

It's not really outdated, it is at the latest release. The release hasn't been made in a while.

Anyway, I'm trying to update it.

It requires a specific version of Qt:

CMake Warning at /usr/local/share/cmake/Modules/CMakeFindDependencyMacro.cmake:48 (find_package):
  Could not find a configuration file for package "Qt5Network" that exactly
  matches requested version "5.11.1".

  The following configuration files were considered but not accepted:

    /usr/local/lib/cmake/Qt5Network/Qt5NetworkConfig.cmake, version: 5.11.2

Call Stack (most recent call first):
  /usr/local/lib/cmake/Qt5WebKitWidgets/Qt5WebKitWidgetsConfig.cmake:73 (find_dependency)
  /usr/local/lib/cmake/Qt5/Qt5Config.cmake:28 (find_package)
  CMakeLists.txt:141 (find_package)
  util/models/CMakeLists.txt:22 (FindQtLibs)

How do I make it to accept any version?

Try rebuilding qtwebkit. Looks like it was built with Qt 5.11.1, while Qt has later been upgraded to 5.11.2.

There is a quirk in FreeBSD ports: QtWebkit has some other version because of some issues. It normally works fine when used with Qt-5.11.2.

How to make leechcraft tolerant to the QtWebkit version? It is normally the REQUIRED keyword, but in this case I don't see it.

Correction: *EXACT keyword.

There is a quirk in FreeBSD ports: QtWebkit has some other version because of some issues.

That's just the same situation as in Gentoo (and some other distros) - looks like it's the new normal as QtWebkit has been long dropped by upstream Qt.

How to make leechcraft tolerant to the QtWebkit version?

Not sure how it works with other cmake projects, but in this particular case it's the qtwebkit itself that's complaining. Indeed, the cmake call stack ends up in /usr/local/lib/cmake/Qt5WebKitWidgets/Qt5WebKitWidgetsConfig.cmake:73. I just double-checked mine, and indeed looks like it only depends on the major-minor pair, not on the major-minor-patch triple (in my particular case, that's just 5.11). Can you paste your /usr/local/lib/cmake/Qt5WebKitWidgets/Qt5WebKitWidgetsConfig.cmake and, perhaps, something like /usr/local/lib/cmake/Qt5WebKit/Qt5WebKitConfig.cmake?

Do you think anything else could be done here, or shall I close this ticket?
