other linker flags are not correct after calabash-ios setup

[niklassaers]

I have a project that includes the -force_load in other linker flags. When Calabash is installed, it is missing -force_load before the "($SRCROOT)/calabash.framework/calabash" linker option

thanks for reporting @niklassaers

reproduced on 0.9.151

i created a sample project here: https://github.com/jmoody/calabash-ios-issue-154

• master branch => before running calabash-ios setup
• issue-154-demo-missing-force-load-for-calabash branch => after running calabash-ios setup

to reproduce:

1. create a new workspace
2. create a new iOS project
3. in the iOS target -force_load the libz.dylib (ignore compiler warnings)
4. build and run to verify you can run the target
5. run calabash-ios setup

expected: other linker flags would include a -force_load before "$(SRCROOT)/calabash.framework/calabash"

found: the flag was missing

This just happened to me now, took a while to figure it out. While this isn't fixed, add a warning to the install instructions.
