I have a big sub-project tree with a combination of C and C++ code on Linux.  
I am trying to get all of the projects to use a common set of compiler arguments.

When I compile my subproject the options.txt does not contain my options.

Any idea on how this can be done?  
I tried binaries instead of components and withType(SharedLibraryBinarySpec) instead of all.

In my root project I have a build.gradle that contains

/\*\* BROKEN build.gradle compiler options are not sent to subprojects. \*/  
allprojects {  
apply plugin: ‘c’  
apply plugin: ‘cpp’  
apply plugin: ‘google-test-test-suite’  
model {  
repositories {  
…  
}  
binaries{  
all {  
cCompiler.args “-Wall”  
cCompiler.args “-Werror”  
cCompiler.args “-g”  
cppCompiler.args “-Wall”  
cppCompiler.args “-Werror”  
cppCompiler.args “-g”  
cppCompiler.args “-std=c++11”  
}  
withType(SharedLibraryBinarySpec) {  
buildable = false  
}  
}  
platforms {  
x86 {  
architecture “x86”  
}  
}  
}  
}
