lrelease-qt5 might be distribution specific

[adlerweb]

There is currently the following definition:
lrelease.commands = $$[QT_INSTALL_BINS]/lrelease-qt5

Arch however features only
$$[QT_INSTALL_BINS]/lrelease
or
/usr/bin/lrelease-qt5

lrelease will be very bad, because it will break the Qt4/Qt5 switch.
QT_INSTALL_BINS is an Qt internal variable. If it is not resolved correct, then the Qt build for Arch Linux is broken. So you must open an bug report for it.

QT_INSTALL_BINS is resolved correctly to the QT5 directory (/usr/lib/qt/bin/). QT4 would be /usr/lib/qt4/bin/ on arch. However the official binary is named just "lrelease". The version ending in "-qt5" is a symlink some distributions add but - as far as I can tell - not part of the official qt5-source. There is no standardized way to install qt4 and qt5 on one system so every distribution has it's own structure. So far I could see the following variants:

Debian: $$[QT_INSTALL_BINS]/lrelease-qt5 (symlink to $$[QT_INSTALL_BINS]/lrelease)
Path = /usr/lib/x86_64-linux-gnu/qt5/bin/lrelease

Arch: $$[QT_INSTALL_BINS]/lrelease or /usr/bin/lrelease-qt5
Path = /usr/lib/qt/bin/lrelease

Gentoo: $$[QT_INSTALL_BINS]/lrelease
Path = /usr/lib/qt/bin/lrelease

Looks like this would get rather ugly to get it portable. I'm not really into cmake, but isn't there any way to let it do the guesswork and just tell it to get the distributions qt5-path? I could see the following lines in other projects, but there where no calls for lrelease - not sure if thats an Option…

• find_package(Qt5Widgets)
• SET (QT_MIN_VERSION "5.5.0")
• There is a ${QT_LRELEASE_EXECUTABLE}

On Fedora/RedHat QT_INSTALL_BINS points to /usr/lib64/qt5/bin/
and lrelease-qt5 -> lrelease

I will try what happens when I use lrelease
