includes in other files

Hello

I'm having troubles using libraries in my sketch location when I want to include them in arduino IDE tabs (.h header files).
IDE somehow skips these includes unless they are in the main program.

For example when I build the main program I get output

Using library Wire in folder: /home/alex/Apps/arduino-1.6.5/hardware/arduino/avr/libraries/Wire 
Using library LiquidCrystal_I2C2004V1 in folder: /home/alex/Dropbox/u1/Arduino/libraries/LiquidCrystal_I2C2004V1 (legacy)

/home/alex/Apps/arduino-1.6.5/hardware/tools/avr/bin/avr-g++ -c -g -Os -w -fno-exceptions -ffunction-sections -fdata-sections -fno-threadsafe-statics -MMD -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO=10605 -DARDUINO_AVR_UNO -DARDUINO_ARCH_AVR -I/home/alex/Apps/arduino-1.6.5/hardware/arduino/avr/cores/arduino -I/home/alex/Apps/arduino-1.6.5/hardware/arduino/avr/variants/standard -I/home/alex/Apps/arduino-1.6.5/hardware/arduino/avr/libraries/Wire -I/home/alex/Dropbox/u1/Arduino/libraries/LiquidCrystal_I2C2004V1 /tmp/build4605378351205613475.tmp/Menus.cpp -o /tmp/build4605378351205613475.tmp/Menus.cpp.o

But when I move includes in one of my class header file I get unrecognized files

/home/alex/Apps/arduino-1.6.5/hardware/tools/avr/bin/avr-g++ -c -g -Os -w -fno-exceptions -ffunction-sections -fdata-sections -fno-threadsafe-statics -MMD -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO=10605 -DARDUINO_AVR_UNO -DARDUINO_ARCH_AVR -I/home/alex/Apps/arduino-1.6.5/hardware/arduino/avr/cores/arduino -I/home/alex/Apps/arduino-1.6.5/hardware/arduino/avr/variants/standard /tmp/build4605378351205613475.tmp/Menus.cpp -o /tmp/build4605378351205613475.tmp/Menus.cpp.o

Error compiling

It seems to me IDE does not parse includes in other files except in main program code - the parameter -I/home/alex/Apps/arduino-1.6.5/hardware/arduino/avr/libraries/Wire -I/home/alex/Dropbox/u1/Arduino/libraries/LiquidCrystal_I2C2004V1 is missing in those...
Is there a workaround?

Correct.

Is there a workaround?

I'm sure that you know the answer to this. You can NOT hide the use of a library from the sketch.
