-## LINUX_CROSS
-
-Setting the `LINUX_CROSS_<name>` environment variable enables cross-compiling
-to Linux for the provided target. The value of the environment variable should
-be the compiler prefix to be used.
-
-For example, to cross-compile for linux-arm with hard floating points
-
-- ensure you have the `g++-arm-linux-gnueabihf` package installed, if your CI
-  is on Ubuntu or Debian
-- set the environment variable `LINUX_CROSS_arm=arm-linux-gnueabihf`
+## Cross Compilation
+
+Setting the `CI_CROSS_TARGETS` environment variable enables cross-compiling
+from Linux to the provided targets architectures.
+The value of the environment variable must  contain the EPICS architecture
+and - depending on the target - may contain additional information like
+the compiler prefix to be used or the version of the target OS.
+
+Multiple cross-targets can be added to the `CI_CROSS_TARGETS` variable
+by separating them with a colon (`:`) character.
+
+For example, possible values are:
+
+- linux-aarch64
+- linux-arm@arm-linux-gnueabi
+- linux-arm@arm-linux-gnueabihf
+- linux-ppc
+- linux-ppc64
+- win32-x86-mingw
+- windows-x64-mingw
