FontConfig misnamed DLL (x64-windows)

[gnieboer]

Host Environment

• OS: x64-windows
• Compiler: VS2019?
• vcpkg date of last pull: 12/3/2020

To Reproduce
Steps to reproduce the behavior:
./vcpkg install cairo
cairo will install fontconfig and then link against it
Run depends.exe or similar on cairo.dll found in .../installed/x64-windows/bin
cairo.dll will be dependent on "libfontconfig-1.dll"
But the fontconfig package installs "fontconfig-1.dll"
so load of the DLL will fail

Failure logs

Additional context
The Cairo cmake cache shows it finding the correct fontconfig.lib file, but in the /lib directory, fontconfig.def ends with "LIBRARY libfontconfig-1.dll", and the .lib file references libfontconfig-1.dll so Cairo is linking to the DLL fontconfig provides, but it doesn't exist as FontConfig actually outputs fontconfig-1.dll (which would be the correct windows naming convention).

Recommend altering the fontconfig build to target that naming standard.

src/Makefile.am line 58 probably needs to be patched from

fontconfig.lib : libfontconfig.la
	lib -name:libfontconfig-@[email protected] -def:fontconfig.def -out:$@

to

fontconfig.lib : libfontconfig.la
	lib -name:fontconfig-@[email protected] -def:fontconfig.def -out:$@
