Question

I have a C++ library that is using cmake. The structure of my library looks like this:

src/module1/class1.h 
src/module1/class1.cpp 
src/module1/class2.h
src/module1/class2.cpp
src/module2/class3.h
src/module2/class3.cpp

etc..

I want to make install rule for my project using INSTALL command. First, i need to retrieve all my headers files:

FILE (GLOB_RECURSE ALL_HEADERS "*.h")

Next i’m trying to install them to C:\temp:

INSTALL(FILES {$ALL_HEADER} DESTINATION "C:\\temp")

It works, but resulting directory is following:

temp/class1.h
temp/class2.h
temp/class3.h

but not is:

temp/module1/class1.h
temp/module1/class2.h
temp/module2/class3.h

As you see CMake doesn’t “remember” folder paths. How can I deal with it?

Answer 1

One of options is using install(DIRECTORY ... syntax:

install(DIRECTORY src/module1 src/module2 DESTINATION "C:/temp" FILES_MATCHING PATTERN "*.h")
