../meson.build:35:4: ERROR: Dependency "libecal-1.2" not found, tried pkgconfig and cmake

Steps to Reproduce

"libecal-1.2" was not found, thats is right, but I guess libecal-1.2 isn't the problem, because libecal-2.0 is installed.

Expected Behavior

pkg-config --libs libecal-2.0

-lecal-2.0 -lical-glib -lical -licalss -licalvcal -ledataserver-1.2 -lsecret-1 -lxml2 -lsoup-2.4 -Wl,--export-dynamic -lgmodule-2.0 -pthread -lgio-2.0 -lgobject-2.0 -lglib-2.0

lldd /usr/bin/evolution | grep ecal libecal-2.0.so.1 => /usr/lib64/libecal-2.0.so.1 (0x00007f9cba05f000)

It will first try to use libecal-2.0 if it is installed but it seems that the development files are not installed on your system.

We can't reproduce the issue on elementary OS, you have to figure-out why your pkg-config used in meson isn't finding your libecal-2.0 library

The Slackware Packagem-Management doesn't split the header files. I could solve the problem, evolution-data-server just needed a rebuild. thanks
