# IMPLICIT_DEPENDS_INCLUDE_TRANSFORM

Specify `#include` line transforms for dependencies in a directory.

This property specifies rules to transform macro-like `#include` lines during implicit dependency scanning of C and C++ source files. The list of rules must be semicolon-separated with each entry of the form `A_MACRO(%)=value-with-%` (the `%` must be literal). During dependency scanning occurrences of `A_MACRO(...)` on `#include` lines will be replaced by the value given with the macro argument substituted for `%`. For example, the entry

    MYDIR(%)=<mydir/%>

will convert lines of the form

    #include MYDIR(myheader.h)

to

    #include <mydir/myheader.h>

allowing the dependency to be followed.

This property applies to sources in all targets within a directory. The property value is initialized in each directory by its value in the directory’s parent.
