Qt5Qml qt5-qtdeclarative-devel

I getting compiler error when trying to build ki18n The error log said:

CMake Error at CMakeLists.txt:42 (find_package):
  Could not find a package configuration file provided by "Qt5Qml" (requested
  version 5.12.0) with any of the following names:

    Qt5QmlConfig.cmake
    qt5qml-config.cmake

  Add the installation prefix of "Qt5Qml" to CMAKE_PREFIX_PATH or set
  "Qt5Qml_DIR" to a directory containing one of the above files. If "Qt5Qml"
  provides a separate development package or SDK, be sure it has been
  installed.

-- Configuring incomplete, errors occurred!

Where the heck is “Qt5Qml”? I try my luck and I am right, the package from repository that I need to be install are qt5-qtdeclarative-devel

$ sudo dnf install qt5-qtdeclarative-devel

Let try to build now

$ kdesrc-build ki18n

nice to see that smiley.

qmake == qmake-qt5

I trying to build KDE dolphin but getting error said:

$ kdesrc-build dolphin
Cloning sysadmin-repo-metadata

Unable to find qmake. This program is absolutely essential for building the modules:

Please ensure the development packages for
Qt are installed by using your distribution's package manager.

 * Aborting now to save a lot of wasted time.
 * export KDESRC_BUILD_IGNORE_MISSING_PROGRAMS=1 and re-run (perhaps with --no-src)
 * to continue anyways. If this check was in error please report a bug against
 * kdesrc-build at https://bugs.kde.org/

So I asked about this on [email protected] mailing list properly. The hint are to check with dnf provides '*/bin/qmake' so the correct package I was looking for are “qt5-qtbase-devel”

$ dnf provides qmake-qt5

another good hint from Rex Dieter to just use builddep to find the requirement / dependencies / packages that needed to build the target software as example:

$ sudo dnf builddep dolphin --assumeno
