What I Found in Code

OCCT/CMakeLists.txt

Line 535 in 1c0bb24

OCCT_IS_PRODUCT_REQUIRED (CSF_TclLibs USE_TCL)

I found that USE_TCL was the only variable that didn't start with CAN.

OCCT/CMakeLists.txt

Lines 534 to 542 in 1c0bb24

	OCCT_IS_PRODUCT_REQUIRED (CSF_FreeImagePlus CAN_USE_FREEIMAGE)
	OCCT_IS_PRODUCT_REQUIRED (CSF_TclLibs USE_TCL)
	OCCT_IS_PRODUCT_REQUIRED (CSF_TclTkLibs CAN_USE_TK)
	OCCT_IS_PRODUCT_REQUIRED (CSF_XwLibs CAN_USE_XLIB)
	OCCT_IS_PRODUCT_REQUIRED (CSF_FREETYPE CAN_USE_FREETYPE)
	OCCT_IS_PRODUCT_REQUIRED (CSF_OpenGlLibs CAN_USE_OPENGL)
	OCCT_IS_PRODUCT_REQUIRED (CSF_OpenGlesLibs CAN_USE_GLES2)
	OCCT_IS_PRODUCT_REQUIRED (CSF_TBB CAN_USE_TBB)
	OCCT_IS_PRODUCT_REQUIRED (CSF_EIGEN CAN_USE_EIGEN)

Maybe, it should be CAN_USE_TCL.

You cannot build Draw Harness without Tcl dependency. USE_TCL is not listed within the OCCT documentation.

If you don't need Draw Harness - you may exclude this module via another parameter BUILD_Draw=OFF, and Tcl dependency will be automatically skipped.

Oh, thanks! I didn't notice that the USE_TCL is't listed!
Well, however, I didn't find that BUILD_Draw is listed within the document, either.
Besides, with that parameter. It still infoed me with -- Info: TCL is used by OCCT.

Sorry, the parameter is called BUILD_MODULE_Draw (the main modules are BUILD_MODULE_FoundationClasses, BUILD_MODULE_ModelingData, BUILD_MODULE_ModelingAlgorithms, BUILD_MODULE_Visualization, BUILD_MODULE_ApplicationFramework, BUILD_MODULE_DataExchange, BUILD_MODULE_Draw).
