I need to add a new INCLUDEPATH into my pro file. The line is follow:

INCLUDEPATH += C:\S60\devices\S60_3rd_FP2_SDK_v1.1\epoc32\include\mmf\server

if I insert this line all work good, but I need to change the start of path with a variable for SDK used. Into project setting-> Build Environment I've the variable EPOCROOT=\S60\devices\S60_3rd_FP2_SDK_v1.1\ but if I change the line with:

INCLUDEPATH += $${EPOCROOT}epoc32\include\mmf\server

the builder doesn't found the include files.

any idea ?
