Bug ID: 1199360
Summary: Parallel build of webkitgtk4 fails with cmake 3.2
Product: Fedora
Version: 22
Component: cmake
Severity: medium

Description of problem: Parallel build of webkitgtk4 fails with cmake 3.2. I
wonder if it's a WebKit bug or a CMake bug.
Version-Release number of selected component (if applicable):
cmake-3.2.0-0.1.rc1.fc22
How reproducible: ...eh... always?
Steps to Reproduce:
1. Revert the latest commit to webkitgtk4 which disables parallel build
2. fedpkg build webkitgtk4
Actual results:
https://kojipkgs.fedoraproject.org//work/tasks/2915/9132915/build.log
The interesting part is this:

Line 1032 of makeprop.pl:
system("\"$gperf\" --key-positions=\"*\" -D -n -s 2 CSSPropertyNames.gperf
--output-file=CSSPropertyNames.cpp") == 0 || die "calling gperf failed: $?";
So I guess CSSPropertyNames.gperf has not been built yet. Oh, but that
file is
built by makeprop.pl, beginning with line 113:
open GPERF, ">CSSPropertyNames.gperf" || die "Could not open
CSSPropertyNames.gperf for writing";
So it doesn't SEEM like a CMake dependency issue... but the script is a
mess to
read, and I can imagine it not working if CSSPropertyNames.in was not
properly
generated.
Now, in WebKit/Source/WebCore/CMakeLists.txt we have this:

Simple, right? :p
And also:

...looks right? At least, I don't notice anything wrong there. But I do
notice

Um, that command is run four times instead of once! And that is as far
as I've
gotten, but I guess that must be a CMake bug.
