Fix CYaml/module.modulemap using relative path

[takasek]

With absolute path I cannot build the project.

This is a result of swift package generate-xcodeproj so automating the replacement in Makefile would be great I think.

+1 for automating the replacement!

@ikesyo Oh, thank you for your advice, but it is too tough for me...
Could anyone fix the problem instead of me?

[ikesyo]

How about something like this:

diff --git a/Makefile b/Makefile
index ae3da88..7fecc79 100644
--- a/Makefile
+++ b/Makefile
@@ -15,3 +15,4 @@ set_version:
 
 generate_xcodeproj:
 	swift package generate-xcodeproj --xcconfig-overrides ${XCCONFIG_PATH}
+	perl -pe 's|".+/(\.build/checkouts/Yams\.git.+)"|"../../../$1"|' -i DIKit.xcodeproj/GeneratedModuleMap/CYaml/module.modulemap

[takasek]

In my environment, it works with duplicating $.

perl -pe 's|".+/(\.build/checkouts/Yams\.git.+)"|"../../../$$1"|' -i DIKit.xcodeproj/GeneratedModuleMap/CYaml/module.modulemap

However, running make generate_xcodeproj extraordinary affects existing files.
Especially it changes the versions from 0.3.0 to 1.0.0.
Any advice to fix it?

Okay, we found it's not so easy to automate xcodeproj generation now. Let's separate the task into 2 peaces, fixing current modulemap and automating xcodeproj generation. This PR does the former task, and I will tackle to the latter task later.

I'm going to merge this PR, thank you @takasek!
